The legislative assembly may enter an agreement with central duplicating services of the office of management and budget to print materials in classifications 1, 2, and 4, before any regular, reconvened, or special session.

The invitation for bids for the classes of printing under this section must include the specifications for form, style, quantity, and timing in accordance with the rules of the senate and house of representatives of the previous legislative session or as directed by the legislative council. All bids must specify the price and cost for which the printing work will be performed and the stock furnished.
